Instructions for Use:  

Surface Preparation  

The key to product performance lies within the preparation of the surface. If you are coating a truck bed, remove all hardware and accessories within the bed that you do not want to be sprayed. You can also remove the tailgate and spray it separately from the rest of the truck. Use acetone or MEK to clean all surfaces of oils, films, and detergents, and then allow them to dry. 

Use wire tape to accurately define the edge of the bed liner for impressively straight cuts. When applying the tape, position it along the desired trim line with the wire side facing the surface. With masking tape and plastic sheeting, cover the rest of the truck and any other areas that will not be coated. Ensure the plastic sheeting is enclosed over the surface to protect from overspray. 

Scuff all surfaces that are to be sprayed with a wire cup brush sander or 40-grit sandpaper. Do not sand to bare metal. Doing so could affect the integrity of the finish and cause the bed liner to peel eventually. Finish preparing the surface by cleaning the newly scuffed surface with acetone or MEK and allow it to dry before proceeding.  

More extensive surface preparation will depend on the substrate, as some may need a primer for ensured adhesion. VFI does not recommend using primers on properly prepared metal surfaces. For other substrates, one of our approved primers may be used to increase adhesion, including VFI-#11, VFI-1016, and VFI-1017. The primer you choose will depend on the substrate. 

Application  

VFI-543 Low Pressure Spray Bedliner must be brought to a minimum temperature of 65°F before use. Premix the B side (poly) until uniform before spraying. Mix times will vary depending on volume and mixing method. The surface temperature should stay between 40°F – 100°F while spraying and curing. If the temperature passes 72°F, the cure speed will increase. 

Wear proper PPE, including an approved respirator, and spray in a well-ventilated area with a low-pressure, plural component spray system. Plan your spray pattern ahead of time to allow for even distribution of the coating. Average coverage for the best results is 80 mils. When spraying a truck bed, VFI recommends starting with the vertical side and back panels before working down toward the end of the bed. As a low-pressure system, VFI-543 creates a rough, consistent texture that is slightly larger than a high-pressure spray truck bedliner. If more texture is wanted, spray over but not directly onto the surface until the desired finish is achieved.  

Allow the material to sit for at least 20 minutes before removing all wire tape, masking tape, and plastic sheeting. To remove the wire tape, pull at a 45-degree angle toward the coated surface. The sprayed surface should be ready for light use in as little as 4 hours and full use within 24 hours. Allow the surface 5 days to cure completely.  

Cleanup  

When cleaning spray equipment, VFI recommends using xylene or MEK. Flush the cleaning solution through the spray lines until the material is completely removed.  

Safety  

*Always read the safety data sheet before working with chemicals 

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste. 

PPE to avoid all unnecessary exposure:  

  • Eye protection – wear safety glasses and any additional eye protection as necessary 
  • Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene) 
  • Skin and body protection – wear suitable protective clothing 
  • Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator 

Product Limitations  

The A side of VFI-543 contains isocyanate, which may irritate the skin and can be toxic if inhaled. Avoid prolonged breathing of vapors and repeated skin contact by wearing the necessary personal protective equipment, including an approved respirator.  

  • Incompatible materials – A side: strong bases, acids, alcohols, amines, and water. B side: oxidizers 
  • Conditions to avoid – heat and incompatible materials  
  • Chemical stability – stable under normal storage conditions  
  • Reactivity & hazardous reactions – no dangerous reactions known under normal conditions 
  • Hazardous decomposition products – may include, and are not limited to, oxides of carbon. Also, oxides of nitrogen and isocyanates for the A side  

Potential Health Hazards  

  • May cause stomach distress, nausea, or vomiting if swallowed.  
  • May cause respiratory tract irritation. Components of the A side may also cause allergy or asthma symptoms and breathing difficulties.
  • Causes skin irritation and sensitization: redness, edema, drying, defatting, and cracking of the skin. Repeated exposure to components of the B side can result in absorption through the skin, causing a significant health hazard.  
  • Causes serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva.  

*If you are experiencing any of these symptoms, seek medical assistance or attention. Call a poison control center or doctor if swallowed.

Frequently Asked Questions

How much does it cost?

VFI strives to keep our prices competitive, but it ultimately depends on the availability of raw materials and the materials used in the formula. Also, polyurea hybrids when compared to pure polyurea coatings provide a good balance of properties, moisture insensitivity, and price.

What happens if the bedliner is damaged? Is it repairable?

Yes, Volatile Free, Inc. offers a bedliner repair material called VFI-520 QS Bedliner Repair that you can use on scratches, blisters, and other damages. It can be applied by brush or injected using the VFI-7500 Qwik Spray Gun.

How to clean spray on bedliner?

Regularly remove dirt, debris, and other grime that has built up from use. You can use a hose or a pressure washer to clean the truck bed with soap and water. Avoid harsh chemicals that may damage the material.

How long do polyurea hybrid coatings last?

When applied correctly and regularly maintained, a spray on truck bedliner should last the entire life of the truck. If repair is needed, VFI offers a thickened polyurea hybrid as a repair material for scratches, gouges, and other blemishes.

Will the bedliner fade over time?

Yes. All VFI bedliners are aromatic, which means they are not UV-stable. If you want to maintain the color of your bedliner, you’ll need to apply a clear aliphatic top coat like VFI-2580.

How soon can the truck bed be used after spraying?

We recommend waiting at least 4 hours after application for light use of your truck bed and a full day (24 hours) before heavy-duty use. The bedliner will gain full strength and formulated properties 5 days after application.

How much material do I need to coat a truck bed?

When spraying VFI-544, we recommend using 6 cartridges (a full case). A full case is just under 2 gallons of material and gets you around 100 mils thick without any loss.

VFI-542 and VFI-543 can be ordered in drums or totes, so about 2 gallons from those containers will also coat one truck bed at around 100 mil thickness without any loss.

How thick should I apply the bedliner?

VFI recommends applying the material at a minimum of 80 mils for long-lasting results.

How long does it take to spray a truck bed?

It can take 2-4 hours to prepare the surface by sanding or priming, tape off areas you don’t want material to get onto, and then spray the truck bed.

Do I need a primer?

Primers are usually not required on properly prepared metal surfaces. Scuff the areas you are coating with a wire cup brush sander or 40-grit sandpaper. If you need a primer, VFI recommends either VFI-1016 Steel Primer or VFI-1017 Porous Surface Primer.

What surface prep is required before applying spray on bedliner?

The surface must be cleaned with acetone before application. Tape up the truck bed with wire trim tape and shield surfaces from overspray with plastic or paper sheets. Scuff sand the area you are coating with a wire cup brush sander or 40-grit sandpaper. Primers are usually not required if the metal is properly prepared.

What temperature should I use the material at?

VFI spray on bedliners must be sprayed between 40°F and 100°F. The cure speed of the material will increase if the temperature passes 72°F.

Does your spray on bedliner come in different colors?

VFI high-pressure, low-pressure, and Qwik Spray bedliners can be pigmented. The premium colors offered are light gray, red, blue, pewter, yellow, and green. These materials are not UV color stable and require an aliphatic top coat like VFI-2580 to prevent fading.

What kind of packaging do your bedliners come in?

For our high pressure bedliner, it can be purchased in drums or totes. The low pressure bedliner can be purchased in pails, drums or totes. The Qwik Spray formula comes in cartridges with 6 cartridges per case.

Is high pressure material better than low pressure material?

While some manufacturers will tell you that high pressure is better than low pressure bedliners, they both perform as expected. Our low-pressure spray bedliner is an economical option with a lower hardness (40 A) and a slightly slower cure than our high-pressure version. It may provide a slightly thicker texture, better for skid resistance. Either version will still provide the same quality and durability.

What are the application options for your bedliner?

VFI spray on bedliner comes in three formulas: high pressure, low pressure, and Qwik Spray for different processing needs.

Does the spray on truck bedliner withstand temperature extremes?

VFI bedliners offer extended protection from wear in extreme temperatures while maintaining flexibility to prevent cracking. They also form a seamless membrane to keep water from penetrating the surface, preventing rust and corrosion.

How are spray in bedliners better than drop in liners?

Spray in bedliners offer more durability than drop in liners. Drop in liners have to frequently be replaced because they crack, break, and warp over time. Spray in bedliners are an almost permanent solution to protect your truck bed. They form a seamless film over the prepared metal to keep out dirt, debris, moisture, and other contaminants. They are more likely to last the entire lifetime of your truck.

What is the difference between an aliphatic and aromatic bedliner?

Aliphatic bedliners are UV stable and will not fade over time, while aromatic bedliners will fade and chalk over time when in direct sunlight. Most bedliner on the market are aromatic, but VFI offers a clear aliphatic top coat to prevent color fading and degradation.

What is your spray on bedliner made of?

VFI’s bedliners are a cost-effective blend of both polyurethane and polyurea. They offer the best characteristics of each material, including properties, cost, and moisture sensitivity.
